As we learn from Newtonian mechanics, motion is relative rather than absolute [1]}, and quantum mechanics further tells us about wave-particle duality [2]}. Nature proves to be highly symmetric and unified. In epistemic logic, agents' instantaneous knowledge is statically represented via current possible worlds [3]}, viz. implicitly through the equivalence class of all the indistinguishable worlds at this moment. Whereas in argumentation theory, the first-class citizens are chronological arguments that are dynamically articulated by different agents so as to attack each other [4]}, explicitly composing a sequential history of a tit-for-tat debate during a period of time.
